Unfortunately, Mr. McKinnon, I don't have a lab to test all those products, so it's just as a general concept. What I'm saying is that if we're strict on caffeine in its chemical form, and we're not strict on guarana, then we're basically not being consistent.
Caffeine is what we call an adenosine antagonist. It acts on the adenosine receptors. Well, my adenosine receptors and yours don't really sense a difference between chemical caffeine and caffeine from a natural source. Given the fact that anywhere on the plant the concentration of caffeine can vary quite a bit, from 2% up to 8%, and there are actually guarana extracts that can go up to 15%, that's a variation that's about fivefold, or even more. I'm not accusing any company here or anything like this; I'm just looking at the current regulation, and I see an imbalance between the two, given the fact that I suspect that guaranine—guarana-containing caffeine—probably doesn't end up in that drink just by pure random chance.
